“…Also, concerns arise about optical instrumentation on board other satellites that may occasionally be in the line of site mentioned. In another experiment [64,65], where it was necessary to point a laser beam towards the International Space Station with the aim of improving the resolution of ground-based photographs of the spacecraft, a complicated procedure was set, including requesting, for any programmed laser ranging, authorization from the Federal Aviation Authority and the Air Force. All the ranging information is acquired as (1) full-rate data i.e., the collection of time of flight (return trip time) from which distance is evaluated and corrected for effects induced, for instance, by the atmosphere, the calibration of the ground station, etc.…”

LAser RElativity Satellite (LARES) is an Italian Space Agency mission that started operations on February 2012 after a successful launch on ESA's VEGA qualification flight. The satellite is covered with retroreflectors that allow accurate laser ranging tracking from the stations of the International Laser Ranging Service. Data of laser ranged satellites are publicly available for scientific analysis and in the case of LARES are being used mainly for testing general relativity and in particular the Lense-Thirring effect due to the rotation of Earth. Although designed for fundamental physics, the LARES mission is also very useful for geodesy and geodynamics and it will provide, among other things, improvement of the International Terrestrial Reference Frame. After a description of the scientific objectives and of the satellite, the paper will focus on the operations required to run the mission.

“…Optics related to CCRs is quite unusual, and it was particularly difficult to prepare a laboratory for testing their properties under space environment [30,31]. However our group acquired some experience with a space CCR during the Specular Point-like Quick Reference (SPQR) experiment conducted on the International Space Station [32,33]. SPQR proved that from ground based photographs, damages on spacecraft could be detected if the atmospheric disturbance is evaluated (by a reflected laser beam from a CCR on board the spacecraft) and removed with proper image processing.…”

On February 13 th 2012, the LARES satellite of the Italian Space Agency (ASI) was launched into orbit with the qualification flight of the new VEGA launcher of the European Space Agency (ESA). The payload was released very accurately in the nominal orbit. The name LARES means LAser RElativity Satellite and summarises the objective of the mission and some characteristics of the satellite. It is, in fact, a mission designed to test Einstein's General Relativity Theory (specifically 'frame dragging' and Lense-Thirring effect). The satellite is passive and covered with optical retroreflectors that send back laser pulses to the emitting ground station. This allows accurate positioning of the satellite, which is important for measuring the very small deviations from Galilei-Newton's laws. In 2008, ASI selected the prime industrial contractor for the LARES system with a heavy involvement of the universities in all phases of the programme, from the design to the construction and testing of the satellite and separation system. The data exploitation phase started immediately after the launch under a new contract between ASI and those universities. Tracking of the satellite is provided by the International Laser Ranging Service. Due to its particular design, LARES is the orbiting object with the highest known mean density in the solar system. In this paper, it is shown that this peculiarity makes it the best proof particle ever manufactured. Design aspects, mission objectives and preliminary data analysis will be also presented.
